The medicine have the advantages that the airfield pavement Rapid-Repair glue of the present invention, it is a kind of cement based of polymer modification Composite, highlight inorganic material be easy to get, good endurance, environmental friendliness, the relatively cheap advantage of price, played high score again The advantage of sub- material high-flexibility.This airfield pavement Rapid-Repair glue, forms polymer in airfield pavement damaged part The cross-linked network structure of hydrolysis product of cement, produces the chemical cohesiveness with mechanical bond and adhesive force, firm with old concrete In conjunction with, formation organic whole, so that airfield pavement is damaged and be able to perfect reparation, and use can be opened quickly.
This airfield pavement Rapid-Repair glue, airfield pavement and other concrete road surface carry out thin layer reparation, equally may be used Used with open quickly.
Specific embodiment
The present invention is described further in conjunction with the embodiments.
A kind of airfield pavement Rapid-Repair glue, the composition of described repair sheets and mass fraction are as follows: cement Part, quartz sandPart, super finely ground slagPart, silicon ashPart, polymeric material Part, water-retaining admixturePart, aqueous alkali agentPart, defoamerPart, coagulantPart, polypropylene fibrePart, thixotropic agentPart.
Wherein, described cement is 42.5 grades of compounding cracking resistance cement, and described quartz sand is sand in quartziferous mechanism, described ultra-fine Breeze is >=s95 level ground granulated blast-furnace slag micropowder, and described redispersable latex powder is import Germany watt gram 5044n, described Water-retaining admixture is hydroxypropyl methyl cellulose (hpmc), and described water reducer is polycarboxylic acid salt's water reducer, and described defoamer is Import p803 organic silicon defoamer, described coagulant is lithium carbonate, and described thixotropic agent is that German import 602 type dry-mixed mortar is special Thixotropic agent.
This airfield pavement Rapid-Repair glue, is added into water and uniformly stirred use, is exclusively used in the fast of airfield pavement equivalent damage Speed is repaired.
This airfield pavement Rapid-Repair glue, in practical application, (as the reparation of larger damage location) can be by matter as needed AmountMix coarse aggregate to use.
The preferably compounding early-strong-fast-hard cracking resistance cement of the present invention is as main Binder Materials so that this airfield pavement Rapid-Repair Glue has the characteristics that early-strong-fast-hard, and beneficial to accelerating open use, usual 3-4 hour just can arrive the indices of open use (such as Reach more than 1.5mpa with old concrete cohesive force).
This airfield pavement Rapid-Repair glue, adds German import anti-saponification hydrophobic type and is resistant to dispersed latex powder, polymer cement ratio Up toSo that hardening repairing body pore structure forms the thin film of continuous closing and has hydrophobicity, steam can freely be arranged Go out, but can resist the erosion to repairing body of aqueous medium and grease medium, and strengthen at double with the cohesive force of old concrete, no Hollowing phenomenon occurs, improves corrosion resistance and the durability of concrete airdrome pavement.
Polymer solidify to form thread film layer and is distributed in whole hardening of cement body, and these thread polymer films are horizontal Defect in across hardening of cement body and micro-crack, and because of its higher cohesiveness and larger tensile strength and deformability, inhale Receive the work to break needed for micro-crack extension, thus effectively having delayed the spreading rate of micro-crack.The polymer of solidification also may be used Pore in filling hardening of cement body, the adhesion of polymer can also strengthen the bonding of cement slurry and aggregate Interface.Therefore, gather Compound is conducive to improving the impervious and corrosion resistance of cement mortar and concrete.
Water-retaining admixture (hpmc), has good water-retaining property with the modified material high tenacity feature of high polymer cement ratio, is entering During row airfield pavement thin layer repairing, also ensure that the unlikely intrinsic rigidity being dehydrated too fast and cement and material of slurry, and affect The hydration and hardening of cement-based gelling material and the normal use of patching material.
Coagulant lithium carbonate makes this airfield pavement Rapid-Repair glue hardening process accelerate.
The incorporation of polypropylene fibre, just as being configured with repair sheets hardenite " mild steel muscle ", improves the toughness of repairing body And splitting resistance.
Thixotropic agent (602) and p803 organic silicon defoamer make this airfield pavement Rapid-Repair rubber cement body cohesiveness, apply Work performance is greatly improved, and the pore structure of airfield pavement Rapid-Repair glue hardenite is optimised.
Silicon ash and slag micropowder all have higher Pozzolanic feature, actual participation master in airfield pavement Rapid-Repair glue The hydration and hardening process of body gelling material, the particularly hydrated product of silicon ash can also penetrate into healant substrate concrete shield duct piece Pore in, not only improve the pore structure of Rapid-Repair glue hardenite, also be beneficial to Rapid-Repair hydration and hardening body and base The interactive connection of layer.
